90 AUSTRALIAN LAND SHELLS. 



tudinally "strigosis" (qu. strigatis-furrowed ?) ; aperture oblong 

 ovate, left lip furnished with a thin callus, right lip simple, arched. 



Length 4 lines ; breadth 2 lines. 



Habitat. Burnside, and hills near Adelaide, S. Australia, beneath 

 bark of gum trees. Angus. 



Not having seen specimens of this small species, I have been obliged 

 to copy the original description. It is stated to be as strictly arbo- 

 real, as S. strigata is terrestrial.

Although this small species is chiefly found under the bark of gum 

 trees, Eucalypti, it is not confined to such situations, but goes out 

 on the branches and leaves of other trees and bushes.
